To all wh0m z't ma concem:

Be 'it known t et I, ULRIG C. DEIKE, a, subject of the King of Great Britain, residing ab Atlanta, in the county ofFulton and State of Georgia, have invented new and; useful Improvements in. Syringes, of which the folloWing is a specification.

The invention is primarily designed t0 supply a syringe- 510 be used as a douche and which embodies concentric syringes, thereby admi&ting of e thorough cleansing with e oxgzpamtively small amount of antiseptie A further purbose of the invention is the rovision o f a syringe of the type stated Which is convenient" t0 use, easily carried, free fromvalves, positive in action, eficient in. operetion with aemall alinount of fluid zmc1 Which admits of the fluid used being wholly recovered together Wi#;h s =acmetim1s 'ILhe invention consists of a syringe embed3ring eo,ncentric pistons, the outer piston forming a harte]. for tne immer piston, the errangemei; being such es to provide Wo distim syringescapable of indep'endemi: 01 eqz njeiet useo The invenioneonsists of the -novel feetures, details of eonstruction and comb ine- 1t ion 0:f pars, whieh hereinafter will be more perticulerly sei; forth, illustrated in the ac companying drawing,encl pointed ou't in the appened cleims.

"Ehe syringe comprises the mein elements' A, B C and D. The element A consists 0f e m erstem 1 hawing a. knob 2 et one end a;1r1d a pisxtoa 3 et the opposite endi. The elet B eomprises a barrel 4: having e pist0;n. 5 et 0116 enciun a eap Gut the opposite ezwl The cep- 6 ris cozme'cted with the bez re i by mea.ng ef e screwthread joini; &D1 is formed centmlly with an opening -of e si'ze ta szqmgly l;@eiVe Ehe 10d er stem 1 of the elemmef; A.

The element D is conical anti is slidable 'upon the 'berrel 7 and sie flexible, being preferably formed of sof& rubber ;to insure e tighlt clesure.

When. the parts are essembledi the element A. 1s arranged to operate within the elememt B, the knob 2 serving es a stop te limit the imv'ard movement of Ehe element and also forming a, grip for the band when withdrawing the element A fromm the element B The elements A e1pd B constitute in efiect e syringe, which may be designate. es the inner syringe in contraistinction &0 the unter syringe formed 'f'oy the el'ements B and C. element B is inserte within the ele ment C, the eap 6 forming both e stop an e han 1oiece. s e stop the part 6 engages the part 9 and limits the imvar movement of the element B.

The method 013 operation; is es follows: Place the rubber guard the apex of the guardi is nol more than two agr1d onehalrc' inches from the tip of the syringe. Place the perforate en ef complete syringe in water, antiseptic, er ether fiui'd thai: may be used, preferably so thai; the perforations extending upfche sides'of the syringe area litisle more than-eovere. Withdraw the wo pistons A ai'1d several times so astoexpel' the air enc1 swell the plungers. Then'eompress en B, an withraw A. so thai: %he immer syringe is completely. fille with fluidi, en w iflzhmw EB, so that the iarger syrihge, er o'uter shefl is a'b0u: half fi1led with '3he fiuii to be use es a douche. Ehe s'yringe is DOW readiy for the douche, and c'are-shoulcl be %aken tha: the rubbet gusird is noi; more inhan half way up the eyiringe, (The -ieeson for this is that' mos'tl of the iseharges andi secretions lodga at {be mouth of 'he womb, anti this is never more than foin" inches imsie an inches). The pistons and B are compre'ssed after insertion, forcing the flui into Ehe vagin,. Pisten B is allowe to rel-wfgallty cf mmuize openmgs. 'ihe elemeni; g

The rubber guarcl hermetically con- .fines the fluid within, and-when thepiston .A is witholrawn, the inner syringe is filled with fluid, thus supplying the douche for the next compression, and so 011.- This would not be possiblewith other makes cf syringes for it is essential to withdravv the piston repeatedly that there be more fiuid 15' in the vagma than the syringe can contain. This is overcome by the positive suction Syringe by the amount of fluid contained in the larger syringe serving as an extra fluid over that which can be contained in the inner syringe, and the additional fact that when holes are provided only in the extreme tip of syringes, as is usual, the flnid discharged, runs down the tubeavvay fr0m the hols in the 611d, and when suction is ap- .the skin from being withdrawn iniso the holes, and reduces the force with vvl1ich Ehe fluiol is discharghdthus protecting the'parts 3from sudden shock, andl alt the sarne time pfoviding sufficient fluid (listurbance 1l:o mach sind cleanse every par thoroughly. So far as is known this repeatingaction is a peculiarity f the positive suction syringe and not possible' With any 0ther make 0I" syringe. Upon completion of this splas'hing an flusl1ing of the fluid, piston A is withdravvn, an piston .lB is withclravvn slowly until every drop cf fluicl is recovere l 85 1ated in greparationfopthorough cleansing together witli all secretions. l*r0m the fact that the piston B gives tl1ree times the suction an holds three timesthe quantity 01' piston A, i'i; will be seen that nisten B can not be entirely withrawn w ithout exerting inore than suflicient snction to entirely recover all tl1e iluid discharged and the extra secretions as Well, which is another peculiarity cf the positive sucftion syringe not incorporate in other syri;nges since the nsual syringe cannot recver more Fluid; than it can contain, and/mence cannot recovef secreitions"in& ldifidn it0 its own capacity without leaving an equal amount of discharged fluid. 'lhe holes running np the sides 0f thesyringe insure an even and general discharge 'and an even an general sucti'on from the entire inner surface, und as the iamete'r of the syringe is purposely made'as large as possible, every fold is diwith but very little fluid. In ordiary syringes, the pipes are small and do not properly dilate the folds, and require much more fluid to do the same amount of cleansing. Also, the large diameter of the'. syringe ng'akes 'improper insertion an impossibility for its large size guides it true. With the -withdraWing of pistons A und B as far as is necessary to recover contents of the vagina, the operation of cleansing is completed, and the whole syringe may be wi th- -dravvn without soiling the clothing 01' leak- In size the outer shell will be not lass thav an inch in-diameter as lass than this would not properly distend the folds. The. othe1 dimensions of the syringe will be practically the same as shown in the dravving, but I do not want to confine myself tothe exact sizes shown, as a Variation of sizes may be a necessity for exceptional cases, (as well as for lengths) nor do I desire to 'confine myself as to the size of perforations or holes.

The favored materialuof manufacture is to be hard rubber, but I may also desire to manufactre of a, combination 0f hard rubber and glass; 01 completely of glass, except the packing, o1 completely of nickeled metal. In -this respect, servicea'bility an cost 0f -producti0n will be considere, an the best article at a r'easonable cost will be adopted.
